The charging port cover on the eOne-Sixty is one of those bits Merida doesn't make easy to source as a spare — official replacements seem to vanish from dealers, which is frustrating when it's a 50p moulding holding back rain from your downtube.
Here's what the community has actually done about it:
Official route first
Try your Merida dealer with the frame's spare-parts number — they can sometimes order the rubber cover even when it's not listed online. Worth a five-minute call before you bodge anything.
The DIY fixes that riders here swear by
•
AliExpress transparent silicon cap —
@Oded sourced an 8mm transparent silicon cap (item 1005001977131330) that fits the standard downtube charging indicator housing. Cheap, and the see-through bit is a bonus — you can read the charge indicator light without popping it.

•
Neoprene + HD velcro —
@Mikerb's fix for when the official cover is unavailable: a bit of neoprene fixed to the frame with heavy-duty adhesive velcro. Not pretty, but it keeps the muck out and it's effectively free.

The transparent cap pairs nicely with another trick from the thread —
@Astro66 noted the clear plug lets you see the charging indicator, where
4 flashes ≈ 80% charge. Handy if you follow the usual battery advice of charging to 80% after each ride and only topping to 100% the night before a big day out.
One reassurance on the water side
Even with a less-than-perfect seal,
@steve_sordy reported zero water ingress problems after 2.5 years of weekly watering-can washes on his 9000 — the battery vents have a thin wall separating them from the cells, so you're not as exposed as you might fear. Worth knowing if you're riding while you wait for a proper replacement.
So: ring the dealer for the genuine part, and if that's a dead end, the AliExpress silicon cap is the cleanest of the DIY options and arguably better than stock for keeping an eye on charge.
If you can tell me whether it's the outer door (the hinged flap) or the actual charge-port plug/seal that's gone — and snap a photo of the markings if there are any — I'll point you at the exact fix.
